CD-ROM Drivers

When the operating system enumerates a CD-ROM device, it loads a native CD-ROM class driver (Cdrom.sys). This driver exposes an I/O control request (IOCTL) interface that is described in the CD-ROM I/O Control Codes section.

The following topics explain some of the key features of the IOCTL interface:

CD-ROM Exclusive Access

CD-ROM Set Speed

CD-ROM Real-Time Streaming

ACLs and the Device Stack
